EU Grocers Pay a Steep Price for Unpatched Fridge Firmware
Hundreds of European grocery stores suffered significant financial losses due to outdated firmware in their refrigeration systems that third-party service providers failed to patch. The incident highlights risks in operational technology (OT) supply chains where outsourced maintenance leaves critical infrastructure vulnerable.
Why it matters: Retailers and facility managers who outsource OT maintenance need to verify that vendors actively patch cooling systems and other critical infrastructure, as unpatched firmware directly exposes stores to costly downtime and data loss.
